1978 Map of Bouldin Island

USGS Topo · Published 1978

About this map

The California Delta's intricate network of levees, islands, and tracts is meticulously documented in this 1970s survey. The landscape is defined by human engineering, featuring the vast Franks Tract (State Recreation Area) and the managed waterways of the Deep Water Channel and Mokelumne River. Dozens of pumping stations and lights facilitate both agriculture and navigation through the winding reaches of the San Joaquin River and Old River.
